Problems in the sum of payoffs

[Andre P]

Hello guys, i'm trying to sum the payoffs in waitpage, so to do this in Group class I created a method set_payoffs, like this:

    def set_payoffs(group):

        p1 = group.get_player_by_role(Constants.p1_role)

        p2 = group.get_player_by_role(Constants.p2_role)

        if group.player_1 == 1 & group.player_2 == 1:

            p1.payoff += 1

            p2.payoff += 1

        elif group.player_1 == 0 & group.player_2 == 0:

            p1.payoff += 0.6

            p2.payoff += 0.6

        elif group.player_1 == 1 & group.player_2 == 0:

            p1.payoff += 0.3

            p2.payoff += 1.2

        elif group.player_1 == 0 & group.player_2 == 1:

            p1.payoff += 1.2

So, following the documentation I tried in a waitpage use after_all_players_arrive, like this:

class ControlWaitPage(WaitPage):

    

    after_all_players_arrive = 'set_payoffs'

But I got a error:

Application error (500)Exception: "set_payoffs" not found in <module 'seller' from '/home/user/otree/project2/seller/__init__.py'>

Not in the Group class. it should be at the outer level, outside of any class.

See examples here: https://www.otreehub.com/code/

and more info here: https://www.otree.org/newformat.html

You can also remove the quotes from 'set_payoffs'.

Chris , tks I'm very grateful

But,  now I have another problem, I made the changes has you suggest, but I got that error:

Application error (500)TypeError: unsupported operand type(s) for &: 'int' and 'Currency'

I need to define in different away the payoff?

[Chris @ oTree]

Don't use "&". use "and"
